Abstract
The invention relates to a method for processing a shaft sleeve, in particular to a method for processing a bimetal shaft sleeve. The first step of pre-processing a steel workpiece is as follows: the inner diameter of the steel workpiece is roughly processed, the outer wall face of the steel workpiece is horizontally placed on a rotary tool device and is remained horizontal, a heating tube is horizontally placed in the inner hole of the workpiece and is arranged in the position of the generatrix rotating downwards with a distance of 30-45 DEG to the extreme lower position of the generatrix, the workpiece is driven to rotate at a low speed by the tool device when the single side of the generatrix of the steel workpiece is heated to the temperature of 1000-1400 DEG C; the second step of copper casting is as follows: the solder is put into the inner hole of the steel workpiece when the single side of the heated generatrix in the first step is rotated to the extreme lower position, the molten copper liquid is pouring into the extreme lower position of the generatrix of the work piece, sealing blocks are arranged on two ends of the steel workpiece, the steel workpiece is rotated for solidifying the copper liquid, and the bimetal shaft sleeve can be obtained after water-cooling to a solidification temperature. The method has simple manufacture process and easy operation, and has the advantages of simple process, saving material and high product performance.
Description
One, technical field:
The present invention relates to the processing method of axle sleeve.
Two, background technology:
Bimetallic bush is to be matrix material with the low carbon steel plate, and the steel copper bimetallic axle sleeve of surperficial sintered copper material, bimetallic bush have the strong characteristics of bearing capacity, be applicable to heavy goods vehicles the balance bridge lining,, the driven pulley of bull-dozer, driving wheel; The excavator interior cover of cranking arm, metallurgical machinery, the heavy industry lifting, mining machinery is a kind of top load low-speed motion axle sleeve of having many uses.At present the processing method of bimetallic bush generally has two kinds, and a kind of is that bimetallic plates with sintering roll, and it is many to add the man-hour treatment process, a seam is arranged on the axle sleeve that this method makes, and influence the mechanical performance of axle sleeve; Another kind method is to water the completely circular structure axle sleeve of casting copper alloys in steel pipe, have to adopt copper metal powder to burn casting, also has to be pressed into after adopting copper iron to process respectively, deficiency is a complex process, the product copper layer thickness of being produced is more than 3 millimeters, and waste of material is bigger, the manufacturing cost height.
Three, summary of the invention:
The objective of the invention is to overcome above-mentioned not enough problem, a kind of processing method of bimetallic bush is provided, technology is simple, and is easy to operate, and cost is low, the products obtained therefrom excellent performance.
The technical scheme that the present invention is adopted for achieving the above object is: the method for processing of bimetallic bush:
First step steel workpiece preliminary treatment: the steel workpiece that steel pipe is processed into Len req, the internal diameter of roughing steel workpiece, the steel workpiece outside wall surface is lain in a horizontal plane on the frock of rotation, make the rotation of the arbitrary bus of steel workpiece maintenance level with the rotation of frock, horizontal positioned heating tube in the workpiece endoporus, heating tube is positioned to bottom rotation and apart from extreme lower position bus 30-45 degree bus place, and heating steel workpiece bus is monolateral during to 1000-1400 ℃, and frock drives workpiece and slowly runs;
The second step cast copper: in the steel workpiece endoporus, put into welding compound when bus is monolateral to rotate to lowest part with heating in the first step, and with the fusing copper water pour workpiece bottommost bus position into, the graphite grazing piece is equipped with at the steel workpiece two ends, the steel workpiece rotation also makes copper water begin to solidify, steel workpiece screwed out the bottommost 30-45 wall of being outside one's consideration and carried out water-cooled to solidification temperature this moment, the bimetallic of finishing a bus is compound, continues to be machined to till the whole complex copper layers of pipe diameter, promptly gets bimetallic bush.
Composite lubricated of described the 3rd step: perforate on the bimetallic bush wall, inlay the lubricated piece of polytetrafluoroethylene (PTFE), promptly get the bimetallic composite shaft sleeve.
It is 1-10 rev/min that described frock drives workpiece rotational frequency.
Described graphite grazing piece is positioned at steel workpiece both ends of the surface bottom, and the sealing block height is greater than copper layer thickness.
Described welding compound is a borax.
The present invention compares with the like product processing method, has outstanding feature, production technology is simple to operation, device therefor is also simple, and bimetallic is heat treated respectively, and is energy-conservation, and then cast in together, the metal bond strength is big, the density height has guaranteed the high strength and the abrasion resistance of product, and the marginal not of limit rotation is simultaneously gone into Tong Shui, copper water flows smooth rapidly, need not post processing, time saving and energy saving, the present invention can be at the little axle sleeve of the degree of wear, be processed into the product of copper layer thickness 1-3 millimeter, under the situation that does not influence normal use, saved the copper product use amount, energy savings.This shows that the present invention has had the advantage that technology is simple, save material, product high-performance aspect concurrently.
